AUTOMATIC CONCEAL'ED FIREARM FOR SELF-DEFENSE.

Application filed. February 1:7, 1928. Serial No. 255,154.

This invention relates to fire arms for personal defense and has for its main object to provide a fire arm which may be secured to the arm of the user and automatically fired upon an appropriate movement of said arm or the finger.

Another object of this invention is to provide a fire arm which may be hidden within the sleeve of the garment of the wearer and fired by the movement of a finger, by the bending of the arm, or by thepressing of the same against the body of the user.

Still a further object of this invention is to provide in combination with a firearm of the character indicated, means whereby said firearm can be easily and securely fastened to the arm of the user and which means will also be adapted'to take up the reaction of the firing of the weapon.-

A further object of this invention is to provide a firearm like 'a pistol of the mentioned character which may be repeatedly fired by the same movement of a part of the body of the user. A

Still a further object of this invention is to provide a concealed weapon for self defense as characterized hereinabove which.

will be light in weight, safe in operation, inexpensive to manufacture and efiicient to apply and to use.

Other objects of my invention will be apparent as the description of the same proceeds. v p p 1 In order that its construction and operation may be readily comprehended, I will now proceed with a full, clear and specific description of the invention, having reference to the accompanying drawings, which show an approved embodiment thereof,and

in which:

Fig. 1 is a side view of a human arm with my invention applied thereto, portions of the sleeve of the garment being broken away for better showing.

Fig. 2 is a similar view wherein, however, a portion of the fastening or retain ing elements for my firearm has been shown in section.

Fig. 3 is an enlarged longitudinal sectional view of the firearm proper, while Figs. 4 and 5 indicate a repeating device for my fire arm before and during the first shot being fired respectively.

Referring now to the drawings with characters of reference,the numeral 10 in dicates the arm of the user with portions of the garment 11' thereon. Resisting, but still flexible strong fabric 12 maybe wrapped around the lower arm of the user, being secured thereon by two straps 13 and 14, :as shown.

indicated in general by the numeral 15, is

The pistol or firearm, proper secured, through means to be described hereinafter, to said piece of fabric 12, preferably a cushioning and positioning piece 16 bemg mterposed between the two.

In Fig. 3 a detailed construction of a preferred embodiment of my firearm is shown. The fire arm has a cylindrical chamber 17 in which may slidably move a "piston 16 steadily urged in a forward direction by a spring 19, but normally kept in a withdrawn position, as shown, by a flat spring 20 engaging a notch 21 in the operating rod 22 attached to the piston 18.

' The pistol barrel proper 23 maybe screwed as at 24, to the front of the casting 25 of the chamber17 and the bore 26 of the barrel may communicate with the chamber 17 through a hole 27. A shell 28 will be placed at the bottom of the bore 26 near the end Wall 29 of the chamber 17 andwhen it is desired to fire the pistol the fiat spring 20 will be withdrawn and the piston 18 will shoot forward, its firing pin 30 passing through the opening 27 hitting the shell 28, causing the sameto explode and to shoot out the bullet 81. A chamber or casing 32 may be provided attached to the casting 25 of the chamber 17 for receiving the mechanism for firing the pistol. Said mechanism may comprise a shaft 33 rotatably arranged in a transversal direction in said casing and having an operating arm 34 and a firing cam arm 35 secured thereon in about the angular deviation shown.

When said two arms are in the position shown by full lines in Fig; 3, the firearm will be at rest and the spring 20 will engage a notch 21 and prevent the firing.

A chain 36 is shown secured to the arm 34 being led. out of the casing 32 through an opening 37, and when this chain is pulled in a forward direction, arm 34 will take up the position indicated by the dot and dash lines, while the cam arm 35 will be pulled into the position indicated in Fig. 5, will engage the spring 20, release it from the notch 21 and the pistol will be fired.

The chain 36 is led in a forward direction preferably being guided by eyelets 38 secured to the barrel, and is fastened to a ring 39 on a finger of the user, as indicated will pull the arm 34 from the position indicated in Fig. 3 by the full lines into about the position indicated by full lines in Fig.

5 and the gun will be fired.

For an efiicient and secure fastening of the-pistol to the lower arm of the wearer I may preferably employ a piece of fabric 12, described hereinbefore,with its two securing straps 13 and 14. A comparatively long piece of material 12 is used so as to distribute the friction and the resistance to move. ment on a larger surface of the arm of the wearer and at the same time enable the straps. 13' and 14 to be placed below and above, respectively, of the widest portion of the lower arm so as to secure the piece of fabric 12 from sliding in either direction. The lower portion of said fabric may then have a lining or inlay 40, preferably of a light sheet metal, which conforms to. the

' contour of the arm and to which the stationary part of the pistol 25 of the pistol 15 may be secured by means of rivet bolts 41 engaging said metalpiece and longitudinal lugs 42 on both sides of the casting 25,. as indicatedin Fig. 2.

After firing, the pistol may be reloaded by removing the same from the arm of the user, withdrawing the .piston 18 by gripping the rod 22 at the handle 43 andpermitting the spring 20 to snap into the notch 21, then unscrewing the barrel 23 and again securing it after a shell has been placed in position.

The arms 34 and 35 will be returned to their original positions through spring 44,

indicated in Fig. 4.

The use of my automatic defense firearm will .be obvious from the description of the same. When it is desired to shoot in selfdefense thearm of the user will be aimed One modification of my firearm to enable the user to fire twice is indicated in Figs. 4 and 5. The gun in this case would have to be provided with two firing chambers and two barrels side by side. A throughgQing shaft- 33 will then have its operating arm 34 loosely secured thereto so that it may rock therearound, a ratchet wheel 45, however, is fast with the shaft 35 and may be operated by the arm 34 through the spring dog 46. When the chain 36 is pulled forward into the position shown in Fig. 5

the gun will be fired as described hereinbefore through the use of the cam arm 35. A second cam arm 47 is, however, also secured fast on the shaft 33 cooperating with a second flat spring 20 engaging a rod 22 and the second gun being placed in parallelism with and close to. the first gun and identical in construction therewith. The first pull on the chain 36 will fire the first gun, as described, whereupon the hand will be relaxed and spring 44 will return the arm 34 into its original position, the two cam. arms 35 and 47 being now in the position indicated in Fig. 5. A second pull on the chain 36 will now obviously bring the arm 47 into engagement with its spring 20 and will cause the second gun to be fired.

It is obvious that any other appropriate part of the arm, finger or hand may be used for the purpose hereinbefo-re described and in a similar manner as the embodiment of, my invention herein specified shows. So, for instance, the bending of the lower arm at the elbow, or the pressing of the lower arm to the body may be used for firing the. gun, in' which case, naturally instead of a chain some other member has to be used which is adapted to transmit a pressure instead of a pull to release the firing pin.

Other obvious changes in the embodiment of my invention may consist in applying the weapon to some other parts of the body and make it adapted to be fired by a movement of an appropriate part of the body making the chain in the herein embodiment adjustable, to different persons; making, the pistol simply strapped to the lower arm, and so on.

Other changes and variations may be made in the construction of the parts within the limits of the claims without departing from the spirit and scope of the invention. As, for instance, my self defense gun may be applied to the arm of the wearer in such a manner as to shoot in a backward direction, or in a multiple gunsome of its units shooting forwardly and some others firing backwardly.

What I claim as new, is:

1. In a weapon for self defense secured to the body of the user, a barrel having two sections, the forward section being a gun proper with a cartridge and the rear section 'in the herein embodiment adapted to be' containing a slidable plunger urged forwardly by a spiral spring; a firing pin at the forward end of said plunger adapted to penetrate through an opening between the two sections and fire said cartridge, but normally being in a withdrawn position; a stem on said plunger to withdraw the same therewith; a flat spring secured on the barrel and engaging a slot in said stem to lock the same in its withdrawn position; a rotatable shaft arranged on said barrel having a cam thereon adapted to engage said fiat spring and withdraw it from said slot, but normally being in an inoperative position; a ring adapted to be worn on the finger of the user; an arm on said shaft; a chain connecting said ring and said arm whereby upon pulling said chain by a movement of the finger said shaft and its cam will be rocked, said flat spring engaged and withdrawn from its slot, causing the gun to be fired.

2. In a weapon for self defense as set forth in claim 1, a plurality of barrels of the construction described in side by side relation, each having a section for the gun proper, a slidable plunger, and a fiat spring normally keeping said plunger in a withdrawn position, and said rotatable shaft transversing the width of the plurality of barrels; said arm being loose on said shaft; a ratchet wheel fast on said shaft and a cooperating ratchet secured on said arm whereby a pull on said chain will rock said shaft; means to return said arm into its position after every pull of said chain, and differently placed cams fast on said shaft each being in connection with one fiat spring for a barrel whereby at every rocking of the shaft another gun will be permitted to fire.
